Electrical Conduction Mechanism for the Investigation of Charge Ordering in Pr0.5Ca0.5MnO3 Manganite System

•The phenomenon of charge ordering (CO) and its associated effects have been demonstrated in Pr0.5Ca0.5MnO3 manganite system by reducing particle size.•The electrical transport property and corresponding parameters were used as a tool to investigate the long-range CO suppression and its crossover.•The observed suppression of CO could be attributed to the surface spin disorder and induced lattice strain effects.
